Abstract

The confocal scanning microscope is a coherent system with significantly improved imaging characteristics. The effective pupil function of such an instrument is a composite one, formed by the convolution of the pupil functions associated with the illuminating and imaging optical systems. Because of this additional degree of freedom, the transfer function of the system can be modified with comparative ease. Confocal imaging will be analysed within a very simple but quantitative physical model. Also, the effect of various pupil combinations on the imaging properties of such systems will be presented with special emphasis on the use of superresolving pupils.
